试一试……

UIButton *finalPriceBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
finalPriceBtn.frame=CGRectMake(260, 25, 45, 15);
[finalPriceBtn addTarget:self action:@selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];
finalPriceBtn.titleLabel.font=[UIFont systemFontOfSize:12];
[finalPriceBtn setTitle:[NSString stringWithFormat:@"$%.2f",tempVal] forState:UIControlStateNormal];
finalPriceBtn.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f  alpha:1];
finalPriceBtn.titleLabel.textAlignment=UITextAlignmentLeft;
[imageView addSubview:finalPriceBtn];

希望我能帮上忙。

你可以在你的ViewDidLoad方法中实现它:

continuebtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 100, view1.frame.size.width-20, 40)];
    [continuebtn setBackgroundColor:[UIColor grayColor]];
    [continuebtn setTitle:@"Continue" forState:UIControlStateNormal];
    continuebtn.layer.cornerRadius = 10;
    continuebtn.layer.borderWidth =1.0;
    continuebtn.layer.borderColor = [UIColor blackColor].CGColor;
    [continuebtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [continuebtn addTarget:self action:@selector(continuetonext) forControlEvents:UIControlEventTouchUpInside];
    [view1 addSubview:continuebtn];

其中continuetonext为:

-(void)continuetonext
{
    GeneratePasswordVC *u = [[GeneratePasswordVC alloc]init];
    [self.navigationController pushViewController:u animated:YES];
}

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(10.0, 100.0, 300.0, 20.0);
[self.view addSubview:button];

UIButton *buttonName = [UIButton
buttonWithType:UIButtonTypeRoundedRect];
[buttonName addTarget:self 
    action:@selector(aMethod:)forControlEvents:UIControlEventTouchDown];
[buttonName setTitle:@"Show View" forState:UIControlStateNormal];
.frame = CGRectMake(80.0, 210.0, 160.0, 40.0); [view
addSubview:buttonName];

finalPriceBtn.titleLabel.textAlignment=UITextAlignmentLeft;
[imageView addSubview:finalPriceBtn];

希望我能帮上忙。

UIButton * tmpBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[tmpBtn addTarget:self action:@selector(clearCart:) forControlEvents:UIControlEventTouchUpInside];
tmpBtn.tag = k;
tmpBtn.frame = CGRectMake(45, 0, 15, 15);
[tmpBtn setBackgroundImage:[UIImage imageNamed:@"CloseButton.png"] forState:UIControlStateNormal];
[self.view addSubview:tmpBtn];
